Auto-Complete Not Functioning when Typiing in Names of Recipients

Until this morning, I used to be able to begin typing a recipient's name when sending an email, and an auto-complete feature would complete the person's name and email address.  This is very convenient, and seemed to be a default.  Suddenly this has changed.  This is inconvenient, as it forces me to have to remember (or look up) all recipient's addresses.  How do I get this feature back?
